Abstract

PURPOSE: To use an easily workable metal such as Al as a base material and to efficiently cut unnecessary IR rays so that visible light is efficiently reflected by using a metal base material having IR absorption layers on both faces.
CONSTITUTION: The metal base material 1 such as Al can be easily formed to a desired shape when subjected to pressing, etc. The IR red absorption layers 2 are formed by vapor deposition, etc. on both the front and rear faces of this base material 1 and further, dichroic films 3 laminated alternately with two kinds of different thin dielectric films are provided on the layers 2 on the front side, by which the metal base dichroic reflecting mirror is formed. The IR rays absorbed by the layers 2 on the front side is released from the layers 2 on the rear side by this constitution. The visible light is thus efficiently reflected by using the easily workable metal such as Al as the base material and efficiently cutting the unnecessary IR rays without entailing an unnecessary temp. increase.
